APPARATUS FOR PRODUCING GAS.

SPECIFICATION forming part of Letters Patent No. 404,322, dated May 28, 1889.

Application filed August 10, 1888.

To all whom it may concern:

Be it known that I, ROBERT R. TURNER,a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Apparatus for Producing Gas, of which the following is a specification.

My invention relates to apparatus for producing gas from liquid hydrocarbons for purposes of heating and illuminating; and the invention consists of the simplified means hereinafter described whereby the hydrocarbon is vaporized and converted by heat into a fixed gas capable of use for the purposes specified.

In the accompanying drawings, Figure 1 is a vertical section through the retort and gen-' crating-furnace, illustrating my invention. Fig. 2 is a horizontal section of Fig. 1, substantially in the line a; 00. Fig. 3 is a detail perspective of the heating-cylinder.

In the said drawings the reference-numeral 1 denotes the brick-work of the furnace, having a fire-box and a grate, 2, above which isarranged an annular shell, 8, resting upon an offset in the brick-work. Arranged concentrically within the shell 3 is aretort, l,having a central contraction or neck, 5, and over the retort extends a horizontal boXconduit-, 6, which descends along the sides thereof to a point directly below the contraction or neck where the box-conduit communicates by elbows with the interior of the retort. The re tort may be conveniently supported within the shell 3 by means of plugs 7, formed upon the latter and having pockets or recesses which receive the elbows of the box-conduit 6. Entering the retort at the top is a pipe, 8, which communicates with the shell 3 in front of a vertical partition or wall, 15, within said shell, to be more particularly described hereinafter. Entering the box-conduit 6 at the top of the retort are two pipes, 9 and 10, adapted to convey steam and oil, respectively, from suitable reservoirs or sources of supply, said pipes having cross-heads or T-heads 12, which open into the box-conduit 6, whereby steam and oil are conveyed to the retort.

The annular shell 3 is provided at regular intervals with alternating baffle-plates 13, Fig. 3, whereby the gas is compelled to traverse Serial No. 282,413. (No model.)

said shell before it is delivered through the exit-pipe 14 in rear of the vertical dividingpartition 15.

The numeral 16 denotes the draft-passage from the fire-box to the chimney '17 at the rear portion of the furnace.

The operation is as follows: A fire being made upon the grate, heating the retort, its box, and the annular shell to a red heat, oil

and steam are forced through the pipes 9 and 10 down through the box-conduit 6. Passing thence into the retort, the oil and steam are converted into vapor and gas, which pass through the neck of the retort into the upper part, where they derive further heat. The vapor and gas then pass by the pipe 8 into and traverse the annular shell 3, and issue therefrom by way of the'eXit-pipe 14 in rear of the partition 15, whereby the vapor and gas are conveyed to any desired point.

A fire-outlet, 18, is formed in the shell 3, and a buttress, 19, in the brick-work is arranged between the draft-opening 16 and said outlet, whereby the products of combustion are compelled to circulate entirely around said shell before passing into the chimney.

Upon the bottom of the retort 4 I prefer to arrange a loose perforated plate, 20, to protect the retort from the direct action of the flames.

The retort may be formed of wrought or cast iron, or of steel.

Nhat I claim is' 1. In a gas-generating apparatus, the combination of a central retort having a box-conduit crossing its top, extending down along its sides, and co mmunicatin g with the retort near its lower end, a surrounding shell containing alternatingbaffle-plates, a pipe connecting the top of the retort with the shell, and oil and steam pipes communicating with the box-conduit, substantially as described.

2. In a gas-generating apparatus, the combination of a central retort, a surrounding shell havinga flue in its side, a pipe connecting the top of the retort with the interior of the shell, an inclosing furnace structure so arranged as to leave a draft-passage around the outside of the shell and provided with a chimney-flue near to the fluein, the shell, but separated immediately therefrom by a buttress or IOC projection in the wall, and a fire-box below the retort com munieating with the flue in the shell, substantially described.

3. In a gas-generating apparatus, the combination of aeentral retort having a box-conduit erossingits top, extending down its sides, and communicating with the lower part of the retort, a surrounding shell containing alternating battle-plates and provided with a fine in its sides, an inclosing furnace structure so arranged as to leave a draft-passage around the outside of the shell and provided with a chimney-flue near to the fine in the shell, but separated immediate-1y therefrom by a but tress or projection in the wall, oil and steam. pipes communicating with the box-conduit, a fire-box below the retort communicating with the flue in the shell, and a pipe conneetin g the top of the retort with the shell, substantially as described.

4. In a gas'generating apparatus, the combination of a central retort havinga box-eonduit crossing its top, extending down its sides, andcommunicating with the lower part of the retort, a surrounding shell provided with a flue in its side, an inelosing furnace structure so arranged as to leave a draft-passage around the outside of the shell and provided with a chimney-flue near to the flue in the shell, but separated immediately therefrom by a buttress or projection in the wall, a lire-box below the vertical retort communicating with the fine in the shell, oil and steam pipes communicating with the box-conduit, and a pipe connecting the retortwith the shell, substantially as described.

5. In a gas-generating apparatus, the combination of a vertical retort having a central contraction and provided with a box-conduit crossing its top and extending down its sides and communicating w1th the lower part of the retort, a surrounding shell containing a partition and alternating baliie-plates and provided with a flue in its side, an inclos'ing furnace structure so arranged as to leave a draft-passage around the outside of the shell and provided with a chimney-flue near to the flue in the shell, but separated immediately therefrom by a buttress or projection in the wall, oil and steam pipes communicating with the box-conduit, a fire-box below the vertical retort communicating with the flue in the shell, a pipe connecting the top of the vertical retort with the shell near the partition within the same, and an exit-pipe from the other side of said partition, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT R. TURNER.
